Filter by:High-Dose Vitamin D3 in the Treatment of Human Immune Deficiency Virus Patients, A Double-Blind Randomized Control Trial Human immunodeficiency virus is a key challenge for global health. Vitamin D deficiency is common in people living with HIV infection. Antiretroviral therapy may create unique risk factors for vitamin D insufficiency, including alterations of vitamin D metabolism by ART.
The objective of the study is to assess the effect of fortified eggs (compared to a non-egg supplemented diet) and intermittent fasting (IF) (compared to a usual care diet) on biomarker profile at 4 months. This will be a 140-participant, 2x2 factorial, randomized clinical trial comparing fortified eggs vs. a non-egg supplemented diet and IF vs. usual care diet through 4 months. Participants will be randomized 1:1:1:1 to the four treatment groups. Participants will have in-person follow-up visits at 1- and 4- months (inclusive of laboratory assessments) in addition to telephone calls at months 2 and 3. A subset of patients (~24 in each egg randomized strata) will undergo microbiome assessment at baseline and at 4 months.
Obesity is a chronic disease in which accumulation of excess body fat can result in impaired health. In cases of severe obesity, weight loss surgery can be necessary as a treatment. There are different forms of surgery but the common basic principle is to restrict food intake and decrease the absorption of food in the stomach and intestines. As a consequence, there is a higher risk of developing nutrient deficiency after surgery and supplementation of protein, vitamins, and minerals can be necessary. This study evaluates intakes of protein, vitamins, and minerals in patients with weight loss surgery and compares them to recommended intakes. Further, this study looks at the role of age, sex, and socioeconomic status in this context.
The purpose of this project is to demonstrate the capability of a standing phototherapy kiosk (SPK) to stimulate cutaneous vitamin D3 and subsequent production of 25 Hydroxyvitamin (OH) D safely and as efficiently as an oral vitamin D3 supplement of 600 IU taken daily over a 10 week intervention period. We will conduct a randomized controlled trial with two treatment arms; ~120 volunteers will be assigned to either the SPK or to a 600 IU daily oral vitamin D3 supplement for 10 weeks. The SPK is an innovative, networked, self-care technology that stimulates endogenous vitamin D production with two ~2-minute treatments per month. It will be tested in an ambulatory setting where enrolled/assigned participants of various baseline levels of 25(OH)D will present for a treatment dose, based on Fitzpatrick skin type category, every other week for 10 weeks. The SPK does not produce a cosmetic tan or dispense pills.
The purpose of this study is to correlate the findings of an early study with current data.
The clinical finding of skin rashes which appear after a vitamin C deficiency in Long Term Care Unit leads us to believe that the institutional diet could predispose to this kind of deficiency. Vitamin C has a key role into the struggle against oxidant stress and is involved into the connective tissue formation of the skin and the vascular endothelium. Vitamin C deficiency affects currently 15 to 25% of the elderly over 65 years old reaching 15% women and 20% men after 65 according to Johnston and Al. It concerns mainly the people in precarious situations (persons without fixed homes, ethyl-smoking persons) and elderly over 65 years. Hypovitaminosis C, defined by plasma level between 5 mg/L and 15 mg/L (28.41 to 85.23 µmol/L), is currently undiagnosed, especially with people with a risk of food deficiency and its prevalence increases with age. The treatment consists of a daily oral supplementation of 1 gram of vitamin C/d for 15 days. A minimum intake of 10 mg/D of vitamin C is required to prevent scurvy and maintain a total pool of 350 mg. A diet modification by a systematic intake of 2 glasses of fresh orange juice and/or the consumption of raw fruits and vegetables would prevent the appearance of scurvy.
Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with the onset or first recognition during pregnancy. The prevalence of GDM varies from 1-14% due to its variability worldwide, depending on the ethnicity, race, and the diagnostic criteria being applied by each country. In addition to this, approximately 7% of all pregnancies are affected by GDM, ending up more than 200,000 women with GDM per year. A recent study of literature research indicated that Middle East and North Africa had the highest prevalence (median, 12.9%) while Europe had the lowest prevalence (median, 5.8%) in the world. In Turkey the prevalence of GDM ranges between 4-10%, based on the reports in different studies. As a growing health concern, GDM has been associated with short and long-term detrimental health outcomes for women and their offspring. Maternal adverse effects of GDM are preeclampsia, elevated risk of development of hypertension, type 2 diabetes mellitus (T2DM), urinary tract infection and comorbidities following delivery. Macrosomia, neonatal jaundice, birth trauma, respiratory distress syndrome, hypoglycemia are included in short term consequence for the neonates whereas risk for development of impaired glucose tolerance, T2DM, obesity, vascular disorders are long term adverse effects on infant's health. The known risk factors for GDM include family history of T2DM, maternal overweight and obesity, advanced maternal age, history of GDM, having macrosomic infant previously, prior fetal death, and race/ethnicity. In addition to these risk factors, recent studies have been suggested that maternal vitamin D deficiency may be associated with a higher risk of GDM. Vitamin D deficiency during the pregnancy has been associated with adverse outcomes for the pregnant women, such as gestational diabetes mellitus, urinary tract infection, preeclampsia, caesarean section during labour [25]. Furthermore, infants born to mothers with lower vitamin D levels have been found to be associated with elevated risk of small for gestational age, low birth weight in the neonatal period, increased risk for cardiovascular disease, respiratory illnesses, type 2 diabetes mellitus in childhood and adulthood. The aim of this study was to compare the serum 25(OH)D levels of women with and without gestational diabetes mellitus (GDM) and identify the serum 25(OH)D level associated with GDM during pregnancy.
500 participants of the vegan/vegetarian congress VegMed are to be included, which should answer once (cross-sectional study) a medicine socio-behaviorist questionnaire on the topic "supplementation of critical nutrients in a plant-based diet" at the VegMed congress on 21/04/2018. The aim of the study is to understand how experts in this field behave and whether actions taken follow official recommendations.
it is a clinical trial to observe increase in serum vitamin D level and clinical symptoms after 3 different doses of cholecalciferol given either intramuscularly or oral.
Age affect insulin sensitivity and the metabolism, and vitamin D status was shown to have a correlation with markers of insulin resistance. That's why, we aimed in our trial to study the effect of vitamin D supplementation on glycemic markers and index of insulin resistance.
